15kV ESD Protected,+2.7V To +3.6V Serial Port Transceiver W/ Green Idle™

The ADM33xxE line of driver/receiver products is designed to fully meet the EIA-232 standard while operating with a single 2.7 V to 3.6 V power supply. The devices feature an on-board Charge Pump dc-to-dc converter, eliminating the need for dual power supplies. This dc-to-dc converter contains a voltage tripler and a voltage inverter that internally generates positive and negative supplies from the input 3 V power supply. The dc- to-dc converter operates in Green Idle mode, whereby the Charge Pump Oscillator is gated on and off to maintain the output voltage at 7.25 V under varying load conditions. This minimizes the power consumption and makes these products ideal for battery-powered portable devices. The ADM33xxE devices are suitable for operation in harsh electrical environments and contain ESD protection up to 15 kV on their RS-232 lines ADM3310E ADM3311E ADM3312E and ADM3315E . The ADM3307E contains ESD protection up to 15 kV on all I/O lines (CMOS, RS-232 EN, and SD). By Analog Devices, Inc.
